Citation | Journal: Drug Discov Today / Year: 2020 Title: Fragment-based drug discovery using cryo-EM. Authors: Michael Saur / Michael J Hartshorn / Jing Dong / Judith Reeks / Gabor Bunkoczi / Harren Jhoti / Pamela A Williams / Abstract: Recent advances in electron cryo-microscopy (cryo-EM) structure determination have pushed the resolutions obtainable by the method into the range widely considered to be of utility for drug discovery. ...Recent advances in electron cryo-microscopy (cryo-EM) structure determination have pushed the resolutions obtainable by the method into the range widely considered to be of utility for drug discovery. Here, we review the use of cryo-EM in fragment-based drug discovery (FBDD) based on in-house method development. We demonstrate not only that cryo-EM can reveal details of the molecular interactions between fragments and a protein, but also that the current reproducibility, quality, and throughput are compatible with FBDD. We exemplify this using the test system β-galactosidase (Bgal) and the oncology target pyruvate kinase 2 (PKM2). | |||||||||
